FELTIA. By Dr. M. Dratjdt. 
Rh. querula Dod. is very similar and most probably only a race or form of the preceding without querula. 
a black band of the collar, a lighter and not grey ground-colour and with a postmedian line being extended 
into long streaks on the veins. 
Rh. albalis Grt. (8 h) has white fore wings dusted with grey and strewn with brownish, with black albalis. 
basal streaks in and below the cell, and small whitish maculae; the transverse lines are mostly absent except 
the undulate line being marked by 3 apical dark patches and 2 in the centre of the marginal area, with large, 
faded whitish spots on its inside; fringes white speckled with dark. Hindwing white with grey-dusted veins 
and marginal area. Utah, Nevada. — f. actona Sm. is smaller, with narrower wings, darker, particularly actona. 
the and the posterior transverse line is distinctly prominent. From Utah. 
Rh. defectipes Dyar, described as Cerapoda and based upon 1 specimen without legs, according to defectives. 
Benjamin belongs hereto and may only be a form of albalis. Grey with a white submedian patch, dark, white- 
striped veins; coniform macula filled up with white, no reniform macula; otherwise very much like the preceding. 
From Montana. 
Rh. cloanthoides Grt. (8h) is very similar, but much darker and more brown, particularly dark in cloanthoi- 
the marginal area behind the undulate line; the black basal rays are longer and of a deeper black; whereas 
in albalis the small white ring-macula is very conspicuous, this is here the case with a white spot at the base 
of the reniform macula. Colorado, Utah, New Mexico, Nevada, and Southern California. 
Rh. insertans Sm. has dirty yellowish forewings and a black-banded collar; the black basal ray is inserlans. 
coherent with the coniform macula; the anterior transverse line is only traceable near the proximal margin; 
the dark-pupilled ring-macula is oblong, connected with the reniform macula, and both are surrounded by 
a continuous black line, the cell before and behind them being black; below the reniform macula there is a 
black spot; the posterior transverse line is extinct; the light undulate line is dentate with black sagittae between. 
Hindwing white. Known from British Columbia. 
Rh. aethes Mob. Forewing ochreous-yellowish white, except a costal-marginal stripe and the basal aethes. 
area dusted with light yellowish-brown; a black basal ray extends to the ochreous-yellow coniform macula 
being surrounded with black; both the upper maculae ochreous, surrounded with black, the reniform macula 
large, above open, on the median angular; posterior transverse line very indistinct; undulate line blackish 
with more or less distinct ochreous dots and black sagittae particularly towards the costal margin. Hindwing 
yellowish-white, towards the margin darkened. Expanse of wings: 34 mm. From Patagonia, the type in the 
Paris Museum. 
Rh. t-nigrum Gn. (7 f) is very easily recognizable by the harpoon-shaped marking of the forewing, t-nigrum. 
being produced by the black median ray with a black crescent of the reniform macula mounted on it; the costal 
half as far as the undulate line is lighter than the other colour. Brazil (Novo Friburgo). 
Rh. tolimae sp. nov. (7 f) may be a form of the preceding; it is larger, the costal half not lighter, the tolimae. 
median ray shorter, not extending beyond the much thicker reniform macula which is black with a deep red 
pupil; behind it a postmedian line is marked by black, strong dots on the veins; the undulate line is only marked 
by 2 subapical and one subanal black spot and does not extend so far towards the cell; forewing and hindwing 
with very strong black dots on the veins. Colombia (Monte Tolima), taken by Fassl. 
Rh. irazuna sp. n. (7 f) probably hardly belongs hereto; it is still larger, the ground-colour of a somewhat irazuna. 
more olive shade, the black median ray is entirely absent, the veins are somewhat lighter and rather conspicuous 
owing to their being finely bordered with brownish; the cerise reniform macula is bordered with black and 
coherent with a black costal spot which surrounds the reniform macula in a flat bow as a dotted line being proxi- 
mally shaded with brownish, and which extends from its lower end vertically to the proximal margin; in the 
centre of the cell there is a fine black dot. Hindwing of the $ dark brownish-grey with lighter fringes. From 
the Volcano Irazu (Costa Rica). 
12. Genus: JFeltla Whr. 
It is said to differ from the preceding by a vertical, ridge-like projection which, however, is only the 
case in about half the species, and by hair-tufts on the outside of the middle and posterior tibiae which are 
strongly spined. Antennae in the first species with long pinnae, then serrate with ciliary tufts, only in clerica 
and agroica plainly tuftedly ciliated. 
F. gladiaria Morr. (= morrisoniana Riley) (8 i) is the only long-combed species with the median gladiaria. 
being on both sides striped white; moreover, all the closely allied species are very similarly coloured and marked; 
also in the marginal area the dark veins are striped white; the $ is usually much darker. Canada and Eastern 
States as far as Texas. 
F. robustior Sm. (8 i) has a very small elliptical ring-macula, the black anterior transverse line is robustior. 
filled up with white, the posterior line being single, distally scaled white. Canada.
